Treatment of 1.385 g of an unknown metal M with an excess of aqueous HCl evolved a gas that was found to have a volume of 382.6 mL at 20.0 degrees C and 755 mmHg pressure. Heating the reaction mixture to evaporate the water and remaining HCl then gave a white crystalline compound, MClx. After dissolving the compound in 25.0 g of water, the melting point of the resulting solution was -3.53 degrees C.
How many moles of H2 gas are evolved?What mass of MClx is formed?What is the molality of particles (ions) in the solution of MClx?How many moles of ions are in the solution?What is the molecular mass of MClx? (Express answer using four significant figures)What is the formula of MClx? (Express answer as a chemical formula)What is the identity of the metal M? (Express answer as a chemical symbol)
